Tunçbilek power station is a 665 MW coal power station in Kütahya, Turkey. It is operated by Çelikler Orhaneli Tunçbilek Elektrik Üretim AŞ [100%]. Based on its capacity (estimated), it can supply roughly 832k homes (estimated). It ranks #131 of 502 Turkey power plants by installed capacity. Commissioned in 1965, it is around 61 years old — an older, legacy facility. In context, coal supplies about 34.3% of Turkey's electricity; the national grid averages 475 gCO₂/kWh (43.3% low-carbon) (2025).

In context: how this plant compares
At 665 MW, Tunçbilek power station is around the median coal plant in Turkey (630 MW). Technically it is described as subcritical. Coal plants burn pulverised coal to raise high-pressure steam for a turbine; they run as baseload but are the most carbon-intensive mainstream source and the first targeted for retirement or efficiency retrofits.
Capacity comparison computed from the WRI Global Power Plant Database; fuel-type context is general engineering background.

Local climate & thermal context
This coal plant burns coal to raise high-pressure steam that spins a turbine-generator. It sits in a warm-summer Mediterranean climate (Köppen Csb) — Northern Hemisphere, latitude 39.6°N — which shapes how much energy it can produce and how its output varies through the year.
Monthly mean temperature
Heating degree-days here run 20% above the median power plant in this dataset — a proxy for how much extra energy heated equipment must replace through its surfaces in winter.
Climate heat-demand index: 61/100 — this site sits in the mid third of the power plants we cover by heating degree-days.
Climate normals: WorldClim 2.1 (1970–2000 monthly normals, 10 arc-min, CC BY 4.0); zone: Köppen-Geiger world climate classification (Kottek et al. 2006, 0.5° grid). Degree-days & heat-demand index computed by PowerAtlas — a modelled heat-demand proxy, not a measured site figure.
Site climate & environmental severity
This site sits in a moderately corrosive environment (estimated ISO 9223 class C3 — Medium), with humidity / wetness the leading environmental stress.
Indicative estimate via the ISO 9223:2012 informative method (atmospheric corrosivity from temperature, time-of-wetness and airborne salinity), using WorldClim climate normals, the Köppen-Geiger class and coast distance. Indicative, not a measured corrosion rate.
